Yang Mingyuan held up a glass petri dish that was slightly rough but still hundreds of years ahead of the manufacturing technology of this era, and carefully shouted something.
"System, apply for acceptance."
[Ding! Ingredient analysis is in progress, please wait!
[The current properties of the petri dish are as follows: hyaluronic acid (microbial fermentation method), purity 0.1%, Which has reached human body absorption standards!
[Congratulations on completing the system test task: making hyaluronic acid!
[You have successfully started the life-related continuous mission: the first step of loving beauty!
[Please use hyaluronic acid to make facial masks and sell them successfully. The profit will be no less than one thousand gold!
[You have obtained the auxiliary book "The Process of Facial Mask"]
A series of prompts sounded in Yang Mingyuan's mind, making him feel happy and sad, and he embarked on the road of setting up a street stall to create the most powerful Tang Dynasty.
